I’ve used Onzow’s cleaner fortunately on an Ortofon Cadenza Black. I’ve usually done this lightly, after playing each side of a record for the past 6 months. Yesterday I used a new Flux Hifi "Flux Sonic" cleaner just once, for the suggested 15 seconds with one drop of cleaning fluid, to see if it made any difference. They say their level of ultrasonic cleaning is set to not harm the stylus.

Luckily I recently bought a UK first press, solid blue triangle, A2/B2 copy of Pink Floyd’s "Dark Side of The Moon" and....well, before the stylus cleaning I wondered what was the fuss about this pressing. Yes, it sounded very good, but the 30th-anniversary pressing might even have just had the edge; however, after the stylus cleaning....WOW!
At the risk of going over the top, hey this is an emotional hobby too, the difference is just stunning to me on my system. There are so many sonic improvements - basically much more detailed, three dimensional sound from bass on up to the top, a slightly wider sound stage.
The record now sounds so different, so fresh, so natural and the band are "in the room"....it is clearly a much better listening experience indeed.
So looking back, the experience with Onzow on the stylus was perhaps akin to being a frog in water, with the water so slowly heating up you do not notice the change. Anyway, my two cents.
For those also using Flux Hifi’s "Sonic Cleaner" how often do you use it please? Thank you very much in advance.
